Our new needle oxygen probes are an industry first. These unique oxygen probes are ideal for measuring headspace in packaging and more.

Available in two different configurations, our needle oxygen probes provide unsurpassed accuracy and ease of use for a variety of applications.

Our needle probes are provided with different overcoats:

1- With no overcoat with a response time (t90) of about 3 Seconds. 

2- With a white acrylic overcoating for reflected signal enhancement with a response time (t90) about 1 min. 

3- With a black acrylic overcoating to protect the sensor from UV, ambient light, environmental effects, and biofouling, with a response time of about 2 min. 

Applications:

·       Monitoring oxygen level of headspace as well as dissolved oxygen in small pharmaceutical packages

·       Oxygen monitoring and profiling of tissue and sediments

·       Extracting sample and real-time oxygen measurement of gas and liquid

  Standard factory calibration is included.
